Light sensor

A light sensor is an input device that measures light levels. Your BBC micro:bit uses the LEDs to sense the levels of light and lets you program your micro:bit as a light sensor.

Watch the video to find out more, then choose one of the projects to turn your micro:bit into a light sensor.

Create a light that turns on when it’s dark

Make an alarm that goes off when lights go on

Temperature sensor

A temperature sensor is an input device that measures temperature. Your BBC micro:bit has a temperature sensor inside the processor which can give you an approximation of the air temperature.

Find out more about the temperature sensor on your micro:bit by watching the video, then choose one of the projects to program the temperature sensor.

Make a simple thermometer with your micro:bit

Pins

On the bottom edge of your BBC micro:bit there are 25 gold strips, called pins. These pins allow you to really get creative. You can create circuits, connect external things like buzzers and motors and make your own fun projects.

Watch the video to find out more about the pins and choose a project to take your making with micro:bit to the next level!

Sound

Your BBC micro:bit can be programmed to make a wide variety of sounds - from single notes, tones and beats to your own musical compositions.

Find out more by watching the video, then choose a project to start making sounds and music with your micro:bit.

USB interface

USBs, or Universal Serial Buses, are are used to connect, communicate and power computers and digital devices.

The BBC micro:bit has a USB interface to allow you to connect your computer to your micro:bit using a micro USB cable and power your micro:bit.

Watch the video to learn more about USB interface on micro:bit and then select one of the projects to start programming the inputs and outputs on your micro:bit.

Processor

A processor is sometimes called the ‘brains’ of a computer and your BBC micro:bit has a micro processor inside it. It’s an essential part of your micro:bit as it runs the programs you write.
